Description

Technical Field

[0001] This utility model relates to the field of fence technology, and in particular to an adjustable wrought iron fence. Background Technology

[0002] Wrought iron fences are structures used to isolate a portion of a site from the external environment, thereby creating a relatively enclosed space. Their design purpose is often adjusted according to needs.

[0003] For example, in a safety fence with existing technology patent number CN222295919U, a rotating rod drives a gear to rotate, and a toothed plate meshes with the gear. The toothed plate is used to lift the top plate to achieve height adjustment of several fence telescopic rods.

[0004] However, existing technologies use two sets of gears and toothed plates on both sides of the fence, driven by two rotating rods. A spring-loaded limiting block locks the rotation of the rotating rods, requiring the springs to be pulled to rotate them. This necessitates at least two workers pulling the springs and maintaining synchronized rotation of the rotating rods to adjust the fence's height. This is not only difficult to operate, but also problematic because the receiving plate secures the tops of several fence telescopic rods. If the rotating rods on both sides rotate at different speeds, the receiving plate may tilt and jam. Therefore, existing technologies have certain drawbacks. This application addresses these problems by providing an adjustable wrought iron fence. Utility Model Content
